My 4 s3's are 'out for delivery' but I havn't paid the VAT yet (20%) Hopefully they'll deliver them with no import costs 
They wont. UPS will collect payment for VAT when delivery takes place. Ah
When my two S3s were delivered I had to pay £122.65 for import duty and UPS handling charge.
I had to pay DHL £153 for 3 batch 3 S3's.
